Apple and Samsung return to federal court in San Jose on Monday, squaring off in a second trial in their global patent feud over the rights to smartphone and tablet innovation.

Apple will resume its legal assault on its South Korean tech rival, accusing Samsung of continuing to copy key features from the iPhone and iPad in more recent lines of products, with billions of dollars at stake in a trial expected to unfold until early May before U.S. District Judge Lucy Koh.

Jury selection is set to begin Monday, with the lawyers likely to make their opening statements to the jury at some point Tuesday.

Apple won the first round against Samsung, persuading a jury in August 2012 to find that Samsung violated Apple's patent rights in a verdict that is now on appeal. Samsung faces close to $1 billion in damages as a result of that trial.

The second trial involves Apple's claims on five patents on devices such as the iPhone 5 and iPad Mini, including the patent on the Siri voice feature, and targets Samsung smartphones such as the Galaxy S3.
